I got the ACM M180A2 in a mystery box. it's hard as ** to pump it especially since mine was basically droned in silicone oil. the shells for mine held 5 at best, otherwise they would all fly out of the shell. at first i thought the red dot was broke but was EXTREMELY dim, after making the hole for the light on the red dot bigger i could barely see it in dim lit conditions and the tactical light's batteries lasted for about a total of a hour of use before the light was too dim to use. both of the attachments use the crappy little watch batteries too which cost me about $5 for three when i keep an entire jar of AA and AAA around the house. so i bought longer screws for the mount and mounted my fancy heavy duty mini LED onto it. I ended up just selling it to a friend for $23 and 4 cans of mountain dew.
that's all i have to say about that
hard to pump
attachments use watch batteries
